illustratingbyvvay of example,zone einbodi; V ment of the invention, asuitable device sup plies the signatures, such as a foldingxor deliverycylinder" 1 or like'device, which receives the signatures fronr'afolding oylinder or other suitable mechanism; In certainkinds'oflnachines a plurality of signal 5 tures are produced across thesheetor web,

the original widesheet being slitfandfolded 1 ery' cha nd s ch j amachine is In the embod'edform, a an interniittently traveling pocketdelivery mechanism is pro:

vided, having 'a transverse series of pockets, V

into each ofvvhioh pockets a'fsignature is simultaneously dropped by thedelivery cyl- When thisjhas been done, the delivery mech- BJIIlSIIIIIIOYGS forward, and the filled series 7 A Successive groups ofsignatures are'jso dropped until the requisite;nu1nb'er of signaturesare built up or superimposed," one on the other, in each ofthe pockets;

the next succeeding group of sequen ially 1e livered ,and superiniposedsignatures. This operation is repeated in succession, so that eachtransverse serles of'pocke'ts will recelve its group of's'uperirnposedor stackedvsigna-f tures and Will then move torvvardftobringf deliverypoint: or station;

the next succeeding, group of pocketsgtothe In the illustratedvforin, aprovided carrying "sprocket. -vvheel's 3 and a.

Upon the sprocket vvheel" 3 is an endless I sprocket chain 5, extendingsubstantially horizontally along the machine, and running also over asprocket wheel 6tfixed to ashaft 7. An endless sprocket chain-8 runsover" the sprocket wheel 4: and also over a sprocket Wheel-9 upon theshaft ,7. Fixed to thesprocket chains 5 and 8 is a series of' vtransverse bars 10, these bars traveling about With-the sprocket chains.The bars 10, are I spaced apart the distance occupied by a pocket, 7 orby the. pockets arranged in transverse series] 'Inthe embodied for-no,the cylinder-'1, as stated, delivers a plurallty of are received end toend bythe respective transversely arranged Pockets, and "with theirfolded edges positioned across or transversely of the machine.

Em "ding longitudinally, t isfin the is same direction as the sprocketchains, and fixed to or supported by the transversebars 10, are tapes orbands llfthese' tapes being located at or near the top and bottom endsof each signature ofthe transverse roup of signatures. At the junctureofeac bar 10 with each band 11 is an upwardly projectingpin or post 13,defining the pocket and serving to keep the signatures in'place'.

In this class of machines, and especially where a collecting and foldingmechanism is employed in connection with rotary perfecting web presses,and the signatures are thus made up from the freshly printed sheets outfrom the perfected web,jitis desirable and necessary that the signaturesbe laid downneatly, compactly, and in register one upon the" other, sothat there may be no doubling back upon themselves of the signavtures'or anypart'thereof, and so that there may be no necessity of laterlining or truing up the signatures in the pile, thereby causin'gsmearing or smutting of ithe freshly printed matter. I With a mechanismof this kind, the folded edge orside 'ofthe signatures (which arepositioned transversely of the machine) spring open more or less,theiebymakihg that side of the pile of signatures much higher'than theopposite side, and consequently causing the signatures to slide one onthe other. a This 'makes'it exceedingly slow and unhandy to pick up thesuperimposed signatures, and also causes smutting of the fresh printingin the necessary jog ging upof the signatures to square them preparatoryto binding. Also the sweep of the delivery cylinder, especially' whenrelatively light weight paper is used, frequently will cause the'upperhalf of the signatures, and sometimes the entire open or front edgethereof, to draw up or to double up, necessitating the smoothingout ofthe signatures,

in addition, tothe difliculties'already stated.

i Means are provided'by this invention for preventing such faults, andthere is provided substantially centrally of each pocket a de vice"across which the' back or folded edge of each signature, as'itisdeposited, is bent or broken, and the signatures are also sup portedin an inclined position and with their ends preferably somewhat lowerthan the middle portion. 4

In" the embodied form there is provided substantially centrally of eachpocket, considered transversely, or along the signature, an upright post17, a series of such posts 17 being in substantiallongitudinalalin'ement 'alo gcthebars l0.- Adjacent its lower end each post 17 isencircled by a collar 18 from whichextends an upwar dly inclined rodl9';ex tending part way'across or along the pocket,"and preferably abouthalf way' across. The collar 18 isadjustable up andv down the-post"17-,- an'dis held in position by sea or'claniping screw 20. Upontheupper part of each post 17 is acollar 21, and extending'inthe'opposite direction from rod 19 and inclined downwardly therefrom is arod 22,extending part way across oralong the pocket. The rod 19 from onepost 17 and i the number of signatures to be laid or su-- perimposed oneupon theother thereon, and

position by a set 'or also to provide proper space for a given ordesired number of signatures,notwithstand ing different weights orthickness of paper being used in the signatures. By reason of thesignature supports being centrally discontinuous, that'is, by reason of'the central break inthe saddles, by the use of the two rods '19 and22,the saddles are adapted. to pass around the sprocket wheels, as" will7 be clearly seen from Fig, 1 of the drawings.

At "the top of each of the posts 17 a "hook or detent 24: is provided,the shank thereof I fitting into ahole in the top of the post 17,

and beingheld in position. by .a screw "25,

screw-threaded into'the post 17 and enga e ing the shank therewithin.The hooks or;

detentsfit Op rate to keep the signatures from being combed over the topof the post 7 by the cylinder 1 from which the signatures are droppedinto the pockets as already dc scribed.- V i There may be used also, ifdesired, fingers 26 suitably supported by a transverse rod 28, andhaving downwardly extending por-' tions' 27, to'insure thefsignaturedropping 1. within the posts 17 and 13.

The signatures are indicated by letters 8. r p
